Stacked type tooling

Abstract

A stacked type tooling is formed by stacking a plurality of slices. Each slice has a plurality of patterned openings. When these slices are stacked together, The patterned openings form at least a cavity. Unnecessary volume of the tooling can be avoided to shrink the size of the tooling and let the tooling be lightweight. Moreover, the manufacturing cost and time of the tooling can be substantially reduced.

1 . A stacked type tooling formed by stacking a plurality of slices, each said slice having at least a patterned opening, said patterned openings forming at least a chamber when said slices are stacked together. 
   
   
       2 . The stacked type tooling as claimed in  claim 1 , wherein said slice is made of metal or refractory material. 
   
   
       3 . The stacked type tooling as claimed in  claim 1 , wherein said patterned opening is formed by cutting using a knife or laser. 
   
   
       4 . The stacked type tooling as claimed in  claim 1 , wherein said slices are stacked together by means of laser spot welding, resistance welding or supersonic bonding. 
   
   
       5 . The stacked type tooling as claimed in  claim 1 , wherein said chamber is a cavity, an ejection passage or a cooling passage. 
   
   
       6 . The stacked type tooling as claimed in  claim 1 , wherein when there are a plurality of chambers, said chambers can be selected among cavities, ejection passages and cooling passages. 
   
   
       7 . The stacked type tooling as claimed in  claim 1 , wherein said slices are stacked together by means of adhesion. 
   
   
       8 . The stacked type tooling as claimed in  claim 7 , wherein the adhesion is accomplished by using an adhesive or in an alloy form.
